Take off fuel pressure from the system, unplug the battery's negative cable, disconnect and remove the airflow filters, then remove the parts connected to inlet and outlet air pipes for the charger cooler. Take the power steering pump and bracket out if it exists, and the alternator. Pull the coolant out of the system first, then take off the turbocharger and expansion tank for more coolant. Take out the
Timing Chain, but first check valve adjustments before starting to take apart the camshafts. Disconnect the power wire from the Camshaft Position sensor, pull out and take off the VCT solenoid valves bolted to the front camshaft bearing cap, then use care to remove both camshafts and lifters while keeping track of their positions. Take out the fuel rail, injectors, and remove all hoses from the coolant outlets. Then disconnect and remove the
Intake Manifold. When an engine support tool or lift prevents us from taking out the cylinder head, we can use a floor jack with a block of wood to hold up the engine from beneath. Carefully cut down the bolt tension on each cylinder head by taking small turning steps back, from newest bolts to oldest, and lift the head out of its place under the hood. When removing the head, protect the aluminum alloy against damage since it is easy to dent. After separating the cylinder head, isolate and throw away the gasket. While cleaning, ensure any locating pins in both the block and head get put back exactly where they belonged. You must wash off all residue on both the cylinder head and block with gasket removal spray, then scrape it clean with rubber or wood tools. Be cautious when cleaning to keep the aluminum alloy intact and stop carbon from getting into oil and water lines. Before putting the pistons in, spread a thin layer of lubricant between the bores and pistons to stop carbon from entering. Check the mating surface for cuts, deep scrapes, and any other damage, and get help from an auto shop if needed. Make sure the mating areas are clean, and place alignment dowels if your vehicle comes with them. Before setting head bolts, make sure the holes are dry to stop water or oil from forcing the pushing rods to lock up. Set the gasket on the cylinder block face with markings upwards, and use guide studs to help you lift the heavy cylinder head into place. Cover the threaded part of each cylinder head bolt with engine oil, put them in place loosely, and work through all bolts in a specific order until they reach their specified torque strength. Along with the other steps, change both your engine oil and filter, and top off the system with fresh fluid.
